The invention relates to a spur gear wheel with a gear body () made from a sintered material, which has a circumference around which teeth () are distributed projecting in the radial direction, and which is delimited by two end faces () in the axial direction. At least one shaped element () in the form of a recess () and/or an elevation () and/or a compacted area is provided on at least one end face () in the region of the teeth () and/or in the radial direction underneath the teeth ().

Gear wheel

A toothed wheel has a sequence of X teeth, wherein each N-th tooth at least partially has a smaller tooth rigidity compared to the remaining X&#x2212;N teeth, N being a number which is selected from a range with a lower limit of 2 and an upper limit of X, in particular X/2. Alternatively, a number of M teeth at least partially have a smaller tooth rigidity than the remaining X&#x2212;M teeth, where M is selected from a range with a lower limit of 1 and an upper limit of X&#x2212;1 or an upper limit of X provided that at least individual teeth are divided or all the teeth have a different geometry, and/or wherein the tooth system has a pitch in which each Nth tooth stands out compared to the remaining X&#x2212;N teeth.
